• How can I easily combine two XML documents with the same parent node into one document? 1 answer

I have a XML file which looks like this:

frankly speaking I have no idea how those scripts worked.

<?xml version="1.0" encoding="UTF-8"?>
    <resource>
        <languages>
            <language>en</language>
            <page1>
                <full_content_text>Full Content Text 1</full_content_text>
            </page1>
            <page2>
                <full_content_text>Full Content Text 2</full_content_text>
    </page2>
 </languages>
 <languages>
    <language>tc</language>
    <page1>
        <full_content_text>Full Content Text tc version 1</full_content_text>
    </page1>
    <page2>
        <full_content_text>Full Content Text tc version 2</full_content_text>
    </page2>
 </languages>
 </resource>

I want to output look like this:

I want to merge the page1 and page2 elements to become page element

<?xml version="1.0" encoding="UTF-8"?>
 <resource>
 <languages>
     <language>en</language>
     <page>
         <full_content_text>Full Content Text 1 Full Content Text 2</full_content_text>
     </page>
  </languages>
  <languages>
     <language>tc</language>
     <page>
         <full_content_text>Full Content Text tc version 1 Full Content Text tc version 2</full_content_text>
     </page>
  </languages>
 </resource>

Code look like this:

$xml = ('test.xml');
$dom = new DomDocument();
$dom->load($xml);
$nodes = $dom->documentElement;
$data = $nodes->getElementsByTagName('languages');

foreach($data as $key => $row){

 $page1 = $row->getElementsByTagName('page1')->item(0);
 $page2 = $row->getElementsByTagName('page2');
 foreach($page2 as $res){

     echo '<pre>';
     print_r($res);
     echo '</pre>';

 }

 $page = $dom->createElement('page', 'Merge Page1 and Page2 Here');
 $row->appendChild($page);

}

$dom->save("merged.xml");

</div>

In php you can try function simplexml_load_file or simplexml_load_file_string $xml=simplexml_load_file("xyz.xml");

Now parse the xml and get the "languages" element temporary store the page1 and page2 element into variable, unset those page1 and page2 element. Now concat page1 and page2 variable. Using addChild Function you can add element to "languages"

After processing convert xml object into string using asXML() And save this string to a xml file.

I hope this may help you to build the logic.
